I have had a Dr.Gas off-road X-pipe for about 2 months now and the thing really smells. I have added MIL-eliminators and it reduced the smell some but its still really bad. For anybody who has a DR.Gas pipe, is there anyway to fit cats on it, I dont see where the heck they would go on mine. Anyways, I dont seem to have lost any power, throttle response is great, and it just screams at WOT, I enjoy going under the bridges in Atlanta, its a riot. What Im getting at is, I just wanna know if the smell is coming from the car running to rich or is it somehting more serious. Since it has gotten cold, you can see the cars exhaust and mine just billows exhuast like a smoke stack, I just hope its not a serious issue.
